75980-60-8
Product name: TPO/Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide
Englishalias:2,4,6-TRIMETHYLBENZOYLDIPHENYLPHOSPHINEOXIDETPO;Diphenyl(2,4,6-trimethylbenzoyl);SPEEDCURETPO;Diphenyl-(2,4,6-Trimethylbenzolyl)-ChemicalbookPhosphineOxide(SP-2,4,6);YF-PITPO;2,4,6-TRIMETHYLBENZOYLDIPHENYLPHOSPHINOXIDE;diphenyl(2,4,6-trimethylbenzoyl)phosphine;IHT-PITPO
CAS: 75980-60-8
Molecular formula: C₂₂H₂₁O₂P
Appearance: White to light yellow crystalline powder
Package: 25kg/drum
Photoinitiator TPO is a highly efficient free radical (1) type photoinitiator that absorbs in the long wavelength range. Due to its wide absorption range, its effective absorption peak is 350-400nm, and it continuously absorbs up to around 420nm. Its absorption peak is longer than that of conventional initiators. After being exposed to light, it can generate two free radicals, benzoyl and phosphoryl, both of which can initiate polymerization. Therefore, it has a fast light curing speed and also has a photobleaching effect, suitable for deep curing of thick films and anti yellowing properties of coatings. It has low volatility and is suitable for water-based applications.

3.AlsoTPO/Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide used as a formylation reagent in the field of fine chemicals
4.Photoinitiator, mainly used for screen printing ink, lithographic printing ink, flexographic printing ink, wood coating
5.Photo initiator, used in various ink industries
6.Mostly used in white systems, it can be used for UV curing coatings, printing inks, UV curing adhesives, optical fiber coatings, etc
TPO is generally considered safe for use in industrial formulations when handled appropriately. It may cause skin and eye irritation. Direct contact with skin and eyes should be avoided. Use in a well-ventilated area and wear suitable protective equipment, including gloves and safety glasses. For detailed handling and risk information, please refer to the Safety Data Sheet (SDS).
Store in a cool, dry, and well-ventilated place.
Keep container tightly closed and sealed until ready for use.
Protect from light and moisture.
Store away from heat and incompatible materials.
TPO is typically packaged in dark-colored bags or drums to protect from light exposure.
Standard packaging includes 1 kg aluminum foil bags, 5 kg carton boxes with inner bags, and 25 kg fiber drums.
Classified as non-hazardous for transport under normal conditions. Always consult the SDS for specific regulations.
